POP Email StopGap

My client will be migrating from POP email servers to Hosted Exchange later in the year.
In the time being, there are several email address(es) that are not getting to the POP email users.
I have cpanel access to the POP email server.
I have ensured that the client's domain is whitelisted and not being blocked by any of the MX providers.

Is there anyway, other than speaking to the owners of the email address(es)/domains to verify why my client's users are not getting emails?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Have you verified that your side or theirs is not blacklisted?

Are you running any kind of spam filters other than the client?

Yes, verified my client is clean, not blacklisted.
It appears the senders email addresses and domains are good also.
Verified that they are also sending to the correct client email addresses.
